Problems Solved
High lubricant consumption from failure at extreme temperatures can present significant operational challenges, as it often leads to increased maintenance costs and unplanned downtime. Poor oxidative stability in competitive grease solutions further exacerbates this issue, since oxidation can cause lubricant breakdown, resulting in sludge formation and decreased performance. Bearing damage or failure from corrosion or rust is another critical problem, especially in environments with moisture or chemicals, as it reduces equipment lifespan and leads to costly repairs or replacements.
MOLYKOTE® 41 Extreme High Temp Bearing Grease is specifically designed to deliver reliable lubrication and safeguard bearings under such hostile operating conditions.
Applications
MOLYKOTE® 41 Extreme High Temperature Grease is particularly well suited for applications and equipment that are subject to high temperatures and harsh weathering, including but not limited to the following:
Conveyor ovens
Oven carts
Steam turbines
Power insulators
